据俄勒冈纪事报报道，美国波特兰大都会地区快线（MAX）轻轨服务站的电梯设备维修及升级服务正式启动。每个轻轨站的月台都有两对电梯，因此可以对两对电梯轮流进行维修。该工程是TriMet长期电梯维修及升级工程的一部分，专门针对轨道交通沿线各站的电梯设备，并从华盛顿公园站开始进行。

　　　PORTLAND METRO ELEVATOR UPGRADES BEGIN

　　Repairs and upgrades on elevators at Portland’s MAX light rail service stations have begun, Oregon Live reports. Each station has two pairs of elevators on the platforms, so one pair can continue to run, while the other is being repaired. Crews began working on the first pair of elevators at the Washington Park station. The upgrades are a part of TriMet’s long-term project of repairing and upgrading all elevators in the metro area’s stations.
